Wow, I've been catching this a lot in the movie-verse now:
-Rips off Bonecrusher's head
-Severely Damages Demolishor's head and pumps a big ass bullet in his face, killing him
-Rips Grindor's face apart
-Shoots part of Megatron's face off
-Rips the Fallen's entire face off!
I guess Freedom isn't the right of Decepticons' faces when it comes to dealing with Optimus.
